[feature]: Support more file type attachment

[benjamreis]

Is there an existing issue for this?

• I have searched the existing issues

Summary

As of now only .zip, .csv, .pdf, common image and video formats are supported - we'd like to attach LibreOffice files as well.

Why should this be worked on?

LibreOffice is a standard tool in many areas and attaching it to an issue would allow to share editables files between the member of the team working on an issue.
